Request Custom Filter not migrated notification after upgrade

Request Custom Filter not migrated notification after upgrade

We have a test server built so we could test the upgrade from 13009 to 14300.  After the upgrade I received a notification as follows:

During the current migration, some request Custom Filter is not migrated due to unsupported fields present in it.

The details of the filters are :
[{"name":"advancedSearch_9605","id":1801,"error":"Description and resolution fields are not supported"}].

To resolve these, please contact support.

The upgrade appears to be successful and I have not found issues navigating through records, reports, etc.  I've tried looking through the logs to see what caused the error, but I haven't found anything.  Is this something I should be concerned about?
